Python中将文件从一个服务器复制到另一个服务器的4种方法

import subprocess

# 定义源文件路径和目标路径
source_file = '/path/to/source/file.txt'
destination_file = 'user@destination_server:/path/to/destination/file.txt'

# 构建 scp 命令
scp_command = f'scp {source_file} {destination_file}'

# 调用 scp 命令
result = subprocess.run(scp_command, shell=True)

# 检查命令执行结果
if result.returncode == 0:
    print('File transfer successful')
else:
    print('File transfer failed')

import paramiko

# 设置 SSH 连接参数
hostname = 'destination_server'
port = 22
username = 'user'
password = 'password'
source_file = '/path/to/source/file.txt'
destination_file = '/path/to/destination/file.txt'

# 创建 SSH 客户端
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname, port, username, password)

# 创建 SFTP 客户端
sftp = client.open_sftp()
sftp.put(source_file, destination_file)

# 关闭连接
sftp.close()
client.close()

print('File transfer successful')

import subprocess

# 定义源文件路径和目标路径
source_file = '/path/to/source/file.txt'
destination_file = 'user@destination_server:/path/to/destination/file.txt'

# 构建 rsync 命令
rsync_command = f'rsync -avz {source_file} {destination_file}'

# 调用 rsync 命令
result = subprocess.run(rsync_command, shell=True)

# 检查命令执行结果
if result.returncode == 0:
    print('File transfer successful')
else:
    print('File transfer failed')

from pysftp import Connection

# 设置 FTP/SFTP 连接参数
hostname = 'destination_server'
username = 'user'
password = 'password'
remote_path = '/path/to/destination/'
local_path = '/path/to/source/file.txt'

# 建立 SFTP 连接
with Connection(hostname, username=username, password=password) as sftp:
    sftp.put(local_path, remote_path)

print('File transfer successful')
